Abstract:This paper studied the impact of the coordinated suitability of the three major resources water-energy-food (WEF) on agricultural output with human capital differences by establishing coupling evaluation model and panel threshold model, based on panel data of 40 agricultural regions in China from 2012 to 2016. The study found that: (1) Most agricultural areas stay on the critical adaptation region or coupling detuning region, and the input and output of WEF system in agricultural areas are not matched on the whole, that is, the redundancy of input elements is serious and the efficiency of resource allocation is low. (2) There are double thresholds between resource suitability and agricultural output. Only when agricultural practitioners reach a higher level of education, the suitability of WEF system has a significant role in promoting agricultural output. The policy implication is that based on the different coordinated suitability level of regions, the governments should carry out resource development and management to improve the allocation efficiency of WEF system according to local conditions. Moreover, relevant talents and rural revitalization program should be put into force, enhancing the positive role of resources coordination and adaptation on agricultural output through transmission effect.
